Transfection is the process of deliberately introducing naked or purified nucleic acids into eukaryotic cells. [ 1 ] [ 2 ] It may also refer to other methods and cell types, although other terms are often preferred: " transformation " is typically used to describe non-viral DNA transfer in bacteria and non-animal eukaryotic cells, including ...
The only essential parts of the T-DNA are its two small (25 base pair) border repeats, at least one of which is needed for plant transformation. [24] [25] The genes to be introduced into the plant are cloned into a plant transformation vector that contains the T-DNA region of the plasmid. An alternative method is agroinfiltration. [26] [27]
Transformation is one of three processes that lead to horizontal gene transfer, in which exogenous genetic material passes from one bacterium to another, the other two being conjugation (transfer of genetic material between two bacterial cells in direct contact) and transduction (injection of foreign DNA by a bacteriophage virus into the host ...
The process of introducing foreign DNA into eukaryotic cells is known as transfection. Electroporation is highly effective for transfecting cells in suspension using electroporation cuvettes. Electroporation has proven efficient for use on tissues in vivo, for in utero applications as well as in ovo transfection. Adherent cells can also be ...
More recently, the transfection of RNAi constructs have been realized as a convenient mechanism for suppressing the expression of a particular gene/protein. DNA can also be inserted into cells using viruses, in methods referred to as transduction, infection or transformation. Viruses, as parasitic agents, are well suited to introducing DNA into ...
The transformation efficiency is then calculated as the percentage of cells that express the fluorescent protein. [5] The number of viable cells in a preparation for a transformation reaction may range from 2×10 8 to 10 11; most common methods of E. coli preparation yield around 10 10 viable cells per reaction.
Insertion of a vector into the target cell is usually called transformation for bacterial cells, [4] transfection for eukaryotic cells, [5] although insertion of a viral vector is often called transduction. [6]
Many methods of transfection and transformation – two ways of expressing a foreign or modified gene in an organism – are effective in only a small percentage of a population subjected to the techniques. [13] [14] Thus, a method for identifying those few successful gene uptake events is necessary.
